Kids and teens should do an hour or more of moderate-intensity to vigorous physical activity each day.That includes running, biking, swimming, walking, jumping rope, skipping, playing basketball or soccer and doing muscle-strengthening activities such as tug of war, modified sit-ups and push-ups.
With so many overweight children, some experts worry that the majority of this generation will be overweight or obese as adults.
Now, a study in today's Journal of the American Medical Association finds that heavy teens often gain a lot more weight in their 20s.
Half of obese adolescent girls and a third of obese teen boys become morbidly obese (80 to 100 pounds overweight) by their early 30s, the research shows.
Experts have known for years that hauling around extra pounds takes a huge toll on children's health.
It puts them at increased risk for type 2 diabetes, high cholesterol, sleep apnea and other health problems.
A study in 2005 found that children today may lead shorter lives by two to five years than their parents because of obesity.About a third of children and adolescents in the United States weigh too much.The exercises can be done with free weights or machines, resistance bands, calisthenics that use body weight for resistance (push-ups, pull-ups, sit-ups), or carrying heavy loads or doing heavy gardening such as digging or hoeing.Older folks should follow the guidelines for other adults if they are able.If not, they should be as active as their physical condition allows.If they are at risk of falling, they should do exercises that improve balance.
